Title: Crystalline maltose from super satd. soln. - prepd. from fermented starch selectively adsorbed on ion exchange resin
IPC: C13K7/00
Filed: 1974-09-09
Abstract: Crystalline maltose is produced by (1) liquefying starch e.g. maize, (2) hydrolysing (1) with beta-amylase at 45-65 degrees C at pH 4.5-6.5 to give a saccharified soln. contg. maltose and dextrin, (3) contacting (2) with an anionic exchange resin (OH- form) selectively adsorbing maltose at 20 degrees C., (4) eluting the maltose from the resin to give a 90% pure soln., (5) concentrating the soln. to 1.03-1.25 degree of super satn., (6) crystallising (5) while maintaining the degree of super sat., (7) separating maltose crystals. Purity of the reaction product can exceed 98%. Crystallisation of maltose occurs only from very conc solns. which cannot be prepd easily by known methods.

Abstract: ABSTRACT OF THE DISCLOSURE         Erratic electrical properties of semiconductor devices made by the thermal gradient zone melting method can result from physical instability of the migrating metal-rich liquid droplets.  By limiting droplet size to a maximum cross-sectional dimension of one millimeter, this cause of defective devices can be eliminated.

Abstract: LIQUID DISTRIBUTOR          Abstract of the Disclosure A liquid distributor for liquid/gas contact apparatus has a liquid feed splitter dividing the liquid supplied thereto at a specific rate of flow into a plurality of streams, and an array of troughs extending across the cross sectional area of the contact apparatus, below the splitter, collects the liquid streams and divides the liquid flowing from the troughs into a greater number of liquid streams.  A shallow pan situated under each of the troughs collects the liquid streams flowing from the troughs and has upturned sides with drain openings therein, of greater number than the liquid streams deposited in the pan, extending upwardly from at least the junction with a downwardly sloping bottom of the pan over which the liquid spreads and flows toward the junction and is again divided into a still greater number of smaller streams as it passes through the drain openings and thereby more uniformly distributed onto a bed of tower packing for contact with a gas flowing therethrough.          Thus, the drain openings extending upwardly from the junction allow the liquid supplied at relatively low rates of flow to pass in relatively thin streams substantially without interference or increasing the level of the liquid in the pans.

Abstract: NOZZLE FOR ROTARY KILN                   ABSTRACT OF THE DISCLOSURE         A nozzle for use with a rotary kiln of the type used for reducing ore, such as iron ore, to a lower state of oxidation.  The nozzle, which may be one of many similar axially and circumferentially spaced nozzles mounted on the kiln, projects in a generally radial direction through the kiln shell to inject fluid into the interior of the rotary kiln.  The nozzle comprises a gas passage for admitting a reductant gaseous fluid such as natural gas (methane) or an oxidizing fluid such as air into the kiln at appropriate times in the cycle of rotation of the kiln.  The nozzle also includes a central oil tube slidably adjustably mounted in a sleeve which extends to the nozzle tip.  The gas passage through the nozzle forms a hollow chamber around the sleeve in which the oil tube is enclosed, whereby the gas passing through the hollow chamber provides a cooling action on the oil tube and on the nozzle tip.  The discharge outlet of the oil tube may be located within its enclosing sleeve in spaced relation to the nozzle tip, and in a cooler zone than the nozzle tip, whereby to minimize clogging of the oil tube discharge outlet by carbon deposits or the like.  By loosening a compression fitting which secures the central oil tube to its enclosing sleeve, the central oil tube may be slidably moved within its enclosing sleeve to permit cleaning of carbon deposits from the nozzle tip.  A quick disconnect coupling at the inlet end of the central oil tube permits disconnection of the oil supply to the oil tube while the kiln is rotating, permitting insertion of a cleaning rod in the oil passage of the central oil tube to "rod out" the central oil tube, the cleaning rod being extendible into cleaning engagement with the nozzle tip.  By loosening the aforesaid compression fitting, with the elements of the quick disconnect coupling also detached, the central oil tube may also be completely removed and replaced with another oil tube while the kiln is rotating.        An important feature of the construction is the fact that the oil passage which forms part of the nozzle structure is fluidly isolated from the passage through the nozzle for the gaseous fluids handled by the nozzle such as natural gas or air.  The inlets of the nozzle to the gaseous fluids and to the liquid hydrocarbon (if used) are connected by valving to the appropriate fluid supply manifolds at appropriate times in the rotation of the kiln.

Abstract: METERING PULSE PUMP               Abstract of the Disclosure A metering pulse pump for metering an additive liquid into a liquid carrier under high pressure.         A high-pressure, rapidly reciprocating piston pump is provided at its outlet end with a pressure-relief valve including a spring pressure control permitting the valve to open under varying pre-set pressure differentials across the valve.  A diaphragm pump having first and second chambers separated by a diaphragm is provided with one of the chambers communicating directly with the outlet of the piston pump upstream of the pressure-relief valve, liquid carrier emitted under pressure from the piston pump serving to drive the diaphragm pump in a pumping stroke, the second chamber of the diaphragm pump having inflow and outflow ports with respective check valves permitting only inflow and outflow of an additive liquid into and out of the second chamber.  The first and second chambers of the diaphragm pump are communicated through a manually closable bleeder duct having a check valve permitting flow only from the first chamber to the second chamber when the duct is open.  The length of a diaphragm pumping stroke corresponding to a rapid piston pump stroke is controlled by the pressure differential setting of the pressure-relief valve.

Horizontal movement in one plane is prevented by the provision of a shoulder on the lid on each side of each ear, and in the other plane by abutment of the connector, or the ears, against the edge of the well or a further shoulder respectively. The slots are sealed by means of a sealant which fills the wells. Upstanding ribs are provided on the upper surface of the lid so as to increase the length of the leakage path between neighboring cells.

A secondary load member is movable relative to the primary load member, and a lift cylinder is connected to the primary load member and the secondary load member to provide relative movement therebetween.  Prevention from overbalancing is provided by sensing a moment created by a load on the apparatus.  A valve simultaneously senses a lift pressure force proportional to a lift pressure in a head end of the lift cylinder and a tilt pressure force propor-tional to a tilt pressure in a rod end of the tilt cylinder.          The valve blocks flow of pressurized fluid from the tilt cylin-der to the tilt cylinder valve and from the lift cylinder valve to the lift cylinder responsive to the greater of the lift pressure force and the tilt pressure force exceeding a prede-termined value.   This is particularly useful in lift trucks wherein the primary load member is a lift truck mast and the secondary load member is the forks of a lift truck.

Abstract: LOOK ASIDE ARRAY INVALIDATION MECHANISM               ABSTRACT This specification describes a virtual memory system in which a set of conversion tables is used to translate an arbitrarily assigned programming designa-tion called a virtual address into an actual main memory location called a real address.  To avoid the necessity of translating the same addresses over and over again, a table called the Directory Look Aside Table (DLAT) retains current virtual to real address translations for use where particular virtual addres-ses are requested more than once.  A counter is associated the DLAT.  Each time a translation is stored in the DLAT the present count in the counter is stored along side the translation.  Each time the DLAT is invalidated the counter is stepped so that with each invalidation a new number is stored in the DLAT with the next translation.  When a translation is read out of the DLAT the number stored with the translation is compared with the present number in the counter.          If they do not match a No Compare signal is provided.          If they match the translation in the DLAT is read out and fed into the directory.
